Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for processing silver halide color photographic materials, and more specifically relates to a method for processing silver halide color photographic materials having a high silver chloride content. The present invention relates to a development processing method using a material (hereinafter simply referred to as a high-silver chloride color light-sensitive material) with improved development characteristics and improved desilvering properties.

(Prior Art) In recent years, in the photographic processing of color photographic materials, it has been desired to shorten the processing time due to the shortening of the finishing delivery time and the reduction of laboratory work.

Increasing the temperature and increasing the amount of replenishment are common methods for shortening the time of each treatment step, but many other methods have been proposed, such as increasing stirring or adding various accelerators.

In particular, for the purpose of speeding up color development and/or reducing the amount of replenishment, color photographic materials containing silver chloride emulsions instead of conventionally widely used silver bromide emulsions or silver iodide emulsions are processed. For example, it is known how to
International Publication No. WO-87-04534 describes a method for rapidly processing high-silver chloride color light-sensitive materials with a color developer substantially free of sulfite ions and benzyl alcohol.

However, it has been found that when the development process is carried out using an automatic paper processor based on the above method, streaky fogging occurs. This is caused by scratches that occur when the photosensitive material comes into contact with rollers, etc. in the developing tank of an automatic processor.
It is estimated that this muscle is a so-called submerged pressure-sensitizing muscle (hereinafter simply referred to as pressure-sensitizing muscle), which causes streak-like fog due to pressure sensitization.

Furthermore, during continuous processing, fluctuations in photographic properties (especially at a minimum of 21 degrees)
It has become clear that the maximum density ([]max)) is significant, desilvering failure occurs, and the white background is significantly contaminated.

As described above, rapid development processing using high-silver chloride color light-sensitive materials has serious problems such as pressure sensitizing streaks, fluctuations in photographic properties, and silver defects, and is not suitable for practical use. There wasn't.

Regarding the above problems, fluctuations in photographic properties during continuous processing,
Among these, fluctuations in photographic properties due to the yellow image forming layer have been a serious problem.

On the other hand, conventional yellow couplers are 4-equivalent couplers or JP-A-50-87650, British Patent No. 3,369.
No. 695, No. 3,408,194, No. 3,415,6
No. 52, 3. 447. No. 928, one hydrogen atom of the active methylene group is replaced by an aryloxy group,
α-acylacetanilides substituted with halogen elements, sulfoxy groups, acyloxy groups, etc. are known, but these couplers have drawbacks such as insufficient coupling reaction activity and significant color fogging. .

JP-A-47-26133 and JP-B-Sho 56-44 have overcome these drawbacks and have more active yellow couplers.
A coupler described in No. 420 in which one hydrogen atom of an active methylene group is directly substituted with a heterocycle containing a nitrogen atom is known, and although it is an improvement over conventional couplers, its effect is insufficient. Met.

Furthermore, in rapid processing methods using high silver chloride color light-sensitive materials, methods for reducing fluctuations in photographic properties (in particular, minimum density (rlmin)) due to continuous processing have been proposed in JP-A-58-15345 and JP-A-59-1999. No. 232,342, it is known to use organic antifoggants. However, it has been found that this method does not prevent the occurrence of pressure-sensitizing streaks and the increase in On+in due to continuous processing, and further increases the occurrence of defective desilvering due to continuous processing.

Furthermore, JP-A No. 61-70552 discloses a method for reducing developer replenishment by using a high-silver chloride color light-sensitive material and adding a sufficient amount of replenishment to prevent overflow into the developer bath during development processing. JP-A-63-106655 describes a method in which a high-silver chloride color photographic light-sensitive material is developed with a color developing solution containing a hydroxylamine compound and chloride at a predetermined concentration or higher for the purpose of processing stabilization. Disclosed. However, these methods are not suitable for practical use because pressure sensitizing streaks, fluctuations in photographic properties during continuous processing, and desilvering failures occur during processing using the automatic processor described above.

As described above, no attempt has been made heretofore to solve the problem of pressure sensitizing streaks that occur during processing using an automatic processor, and improvements have been desired.

Furthermore, there has been a strong desire for a technique that can resolve pressure sensitizing streaks without causing fluctuations in photographic properties during continuous processing, particularly fluctuations in photographic properties of yellow images, or defective desilvering.

(Problem to be solved by the invention) Therefore, an object of the present invention is to use a high-silver chloride color light-sensitive material, which has improved pressure sensitization, and which is rapid and stable even during continuous processing. The object of the present invention is to provide a processing method that exhibits photographic properties.

In addition, it is an object of the present invention to provide a color development processing method that uses a high-silver chloride color light-sensitive material, has a small amount of residual silver, and has improved desilvering properties.

The high silver chloride color light-sensitive material of the present invention may be constructed by coating at least one blue-sensitive silver halide emulsion layer, one green-sensitive silver halide emulsion layer, and one red-sensitive silver halide emulsion layer on a support. can.

In color photographic paper (a), these photosensitive emulsion layers are usually coated on the support in the above order, but they may be applied in a different order. The subtractive color method is achieved by incorporating a silver halide emulsion sensitive to the wavelength range of Color reproduction can be performed. However, the coloring hue of the angry light layer and the coupler may not correspond to each other as described above.

As the silver halide emulsion of the present invention, a so-called high silver chloride emulsion having a high silver chloride content is used. The silver chloride content of these is 80 mol% or more, preferably 95 mol%
More preferably, the amount is 98 moles or more.

As the silver halide emulsion used in the present invention, one consisting of silver chlorobromide or silver chloride that does not substantially contain silver iodide can be preferably used. Here, "substantially free of silver iodide" means that the silver iodide content is 1 mol% or less, preferably 0.2 mol% or less, even if the halogen composition of the emulsion differs between grains. Although they may be equal, if an emulsion having an equal halogen composition among the grains is used, it is easy to make the properties of each grain uniform. In addition, regarding the halogen composition distribution inside silver halide emulsion grains, there are grains with a so-called uniform structure in which the composition is the same in every part of the silver halide grain, and grains with a core inside the silver halide grain and a shell surrounding it. (Shell) (- A place where the halogen composition differs between layers or multiple F layers 17f? A particle with type II structure, or a structure with a non-layered portion with a different halogen composition inside or on the particle surface (if it is on the particle surface, the particle Particles with a structure in which parts of different compositions are joined on the edges, corners, or faces of It is advantageous to use silver halide grains, which is also preferable from the viewpoint of pressure resistance.If the silver halide grains have the above-mentioned structure, even if the boundaries between parts with different halogen compositions are clear boundaries, the composition A mixed crystal may be formed due to the difference, and the boundary may be unclear (or it may be one that actively has a continuous structural change).

Such a high silver chloride emulsion preferably has a structure in which the silver bromide localized layer is inside and/or on the surface of the silver halide grains in a layered or non-layered manner as described above.The halogen composition of the localized layer is・The silver bromide content is preferably at least 10 mol%, more preferably more than 20 mol%, and these localized layers are inside the grain, on the edge, corner, or surface of the grain surface. However, one preferred example is one in which part of the corner of the particle is epitaxially grown.

On the other hand, in order to minimize the decrease in sensitivity when a photosensitive material is subjected to pressure, even in high silver chloride emulsions with a silver chloride content of 90 mol% or more, grains with a uniform structure with a small distribution of halogen composition within the grains are used. It is also preferable to use

Furthermore, it is also effective to further increase the silver chloride content of the silver halide emulsion for the purpose of reducing the amount of replenishment of the development processing solution.

In such cases, the silver chloride content is 98 mol% to 10
Emulsions of almost pure silver chloride, such as 0 mol %, are also preferably used.

Average grain size of the silver halide grains contained in the silver halide emulsion used in the present invention (the grain size is defined as the diameter of a circle equivalent to the projected area of the grain, and the number average thereof is taken)
is preferably 0.1μ to 2μ.

In addition, the particle size distribution is preferably so-called monodisperse with a coefficient of variation (standard deviation of particle size divided by average particle size) of 205≦ or less, preferably 15% or less. In this case, a wide latitude can be obtained. The above monodispersed emulsions may be blended in the same layer for the purpose, or MN

A method in which particles are formed in an atmosphere containing excess silver ions (so-called back mixing method) can also be used.

As one type of simultaneous mixing method, it is also possible to use a method in which the pAg in the liquid phase in which silver chloride is produced is kept constant, that is, the so-called Chondral double jet method. According to this method, a silver halide emulsion having a regular crystal shape and a nearly uniform grain size can be obtained.

Various polyvalent metal ion impurities can be introduced into the silver halide emulsion used in the present invention during the process of emulsion grain formation or physical ripening.

Examples of compounds used include cadmium, zinc, lead,
Salts such as copper and thallium, or iron, which is a group II element,
Examples include salts or complex salts of ruthenium, rhodium, palladium, osmium, iridium, platinum, and the like. In particular, the above-mentioned Group Ⅰ elements can be preferably used. The amount of these compounds added varies over a wide range depending on the purpose, but is preferably 10-1 to 10-'' mol based on the silver halide.

The silver halide emulsion used in the present invention is usually subjected to chemical sensitization and spectral sensitization.

Regarding the chemical sensitization method, sulfur sensitization typified by the addition of unstable sulfur compounds, noble metal sensitization typified by gold sensitization, or reduction sensitization can be used alone or in combination. Regarding compounds used for chemical sensitization, see the lower right column on page 18 of the specification of JP-A-62-215272.
Those described in the upper right column of page 22 are preferably used.

Spectral sensitization is performed for the purpose of imparting spectral sensitivity in a desired light wavelength range to the emulsion of each layer in the light-sensitive material of the present invention. It is preferable to add an absorbing dye-spectral sensitizing dye. Examples of the spectral sensitizing dye used in this case include F, Il, IIarmer 11

These are commonly called photographic stabilizers. As specific examples of these compounds, those described on pages 39 to 72 of the specification of JP-A-62-215272 mentioned above are preferably used.

The emulsion used in the present invention may be either a so-called surface latent image type emulsion in which a latent image is mainly formed on the grain surface or a so-called internal latent image type emulsion in which a latent image is mainly formed inside the grain. Also good.

The total coating amount of silver in the high silver chloride color light-sensitive material of the present invention is 0.7
It is necessary that it is 5 g/nf or less.

Preferably it is 0.65 to 0.4 g/Po, and the amount of coated silver is within a preferable range and Dmax is excellent.

If the total amount of coated silver is more than 0.75 g/ITI, the photographic properties will fluctuate greatly due to continuous processing, and furthermore, the amount of silver remaining after processing will be large, making it impossible to achieve the object of the present invention.

More than one type of inorganic acid, organic acid, alkali metal or ammonium salt thereof, or a g6+ inhibitor such as ammonium nitrate or guanidine can be added.

The fixing agent used in the bleach-fixing solution or fixing solution according to the present invention is a known fixing agent, namely sodium thiosulfate,
Thiosulfates such as ammonium thiosulfate; thiocyanates such as sodium thiocyanate and ammonium thiocyanate; water-soluble such as thioether compounds and thioureas such as ethylene bisthioglycolic acid and 3,6-cythia-1,8-octanediol These silver halide solubilizers can be used alone or in combination of two or more. Also, JP-A-55-1553
A special bleach-fixing solution consisting of a combination of the fixing agent described in No. 54 and a large amount of a halide such as potassium iodide can also be used. It is preferable to use
The amount of fixing agent per 11 is preferably 0.3 to 2 mol,
More preferably 0. It is in the range of 5 to 16.0 moles.

The pH range of the bleach-fix solution or fixer solution in the present invention is as follows:
3 to 10 are preferred, and 5 to 9 are particularly preferred.
If the pH is lower than this, the desilvering performance is improved, but the deterioration of the solution and the leucoization of the cyan dye are accelerated. On the other hand, if the pH is higher than this, desilvering is delayed and staining is more likely to occur.

p) (To adjust, add hydrochloric acid, sulfuric acid,
Nitric acid, acetic acid, bicarbonate, ammonia, caustic potash, caustic soda, sodium carbonate, potassium carbonate, etc. can be added.

Further, the bleach-fix solution may contain various other optical brighteners, antifoaming agents, surfactants, and organic solvents such as polyvinylpyrrolidone and methanol.

The bleach-fix solution and fixer solution used in the present invention contain sulfites (e.g., sodium sulfite, potassium sulfite,
ammonium sulfite, etc.), bisulfites (e.g. ammonium bisulfite, sodium bisulfite, potassium bisulfite, etc.), metabisulfites (e.g. potassium metabisulfite, sodium metabisulfite, ammonium metabisulfite, etc.) ) and other sulfite ion-releasing compounds. These compounds are approximately 0.0 in terms of sulfite ion.
The content is preferably 2 to 0.50 mol/l, more preferably 0.04 to 0.40 mol/l.

Sulfites are commonly added as preservatives, but other preservatives include ascorbic acid, carbonyl bisulfite adducts,
Sulfinic acids, carbonyl compounds, sulfinic acids, etc. may be added.

Furthermore, buffering agents, optical brighteners, chelating agents, antifungal agents, etc. may be added as necessary.

After fixing the silver halide color photographic light-sensitive material of the present invention or desilvering treatment such as bleach-fixing, it is generally subjected to a washing and/or stabilizing process.

The amount of water used in the washing process depends on the characteristics of the photosensitive material (for example, depending on the materials used such as couplers), the application, the temperature of the washing water, the number of washing tanks (the number of stages), the replenishment method such as countercurrent or forward flow, and various other conditions. Can be set over a wide range. this house,
The relationship between the number of flushing tanks and water in the multi-stage countercurrent system is described in the Journal on the Society on Morsilan.
Picture and Television Engineers (
Journal of the 5ociety of
Motion Picture and Terevi
Sion Engineers) Volume 64 Sp, 248
-253 (May 1955 issue).

According to the multi-stage countercurrent method described in the above-mentioned literature, the amount of water used for washing can be significantly reduced, but due to the increase in the residence time of water in the tank, bacteria will breed, and the generated suspended matter will adhere to the photosensitive material. In the processing of the color photosensitive material of the present invention, as a solution to such problems,
The method for reducing calcium and magnesium described in Japanese Patent Application No. 61-131632 can be used very effectively. In addition, chlorine-based disinfectants such as isothiazolone compounds, cyabendazole, chlorinated sodium isocyanurate, and other benzotriazoles described in JP-A No. 57-8542, "Chemistry of Antibacterial and Antifungal Agents" by Hiroshi Horiguchi It is also possible to use disinfectants described in ``Sterilization, sterilization, and anti-mildew technology of microorganisms'', Hygiene Techniques Section, and ``Encyclopedia of Antibacterial and Antifungal Agents'', Section of the Japan Antibacterial and Antifungal Society.

The pH of the washing water in the processing of the photosensitive material of the present invention is 4 to 9.
and preferably 5 to 8. The washing water temperature and washing time can also be set variously depending on the characteristics of the photosensitive material, its use, etc., but generally it is 20 seconds to 10 minutes at 15 to 45°C, preferably 25 to 45°C.
The range of 30 seconds to 5 minutes at ~40℃ is i! 1 translated.

Furthermore, the photosensitive material of the present invention can also be directly processed with a stabilizing solution instead of washing with water. In such stabilization treatment, Japanese Patent Application Laid-Open Nos. 57-8543 and 5B-1
No. 4834, No. 59-184343, No. 60-220
No. 345, No. 60-238832, No. 60-2397
All known methods described in No. 84, No. 60-239749, No. 61-4054, No. 61-118749, etc. can be used. Especially 1-hydroxyethylidene-1,1-diphosphonic acid, 5-chloro-2-methyl-
A stabilizing bath containing 4-isothiazolin-3-one, a bismuth compound, an ammonium compound, etc. is preferably used.

Further, following the water washing process, a further stabilization process may be performed, such as a stabilizing bath containing formalin and a surfactant, which is used as a final bath for color photosensitive materials for photography. .

The processing time of the present invention is defined as the time from when the photosensitive material comes into contact with the color developer until it leaves the final bath (generally water washing or stabilization tower).
The effects of the present invention can be significantly exhibited in a rapid treatment process in which the processing time is 30 minutes or less, preferably 4 minutes or less.

Next, Samples 02 to 05 were prepared in the same manner as Sample 01, except that the halogen compositions of the 1.3 and 5N silver halide emulsions were changed as shown in Table 1.

Table 1 Subsequently, samples were prepared by replacing the 3N yellow coupler with the coupler Y-11 of the present invention in an equimolar amount, making the halogen composition of the emulsion used exactly the same as in Table 1, and leaving the rest unchanged. These samples are designated as 06-10.

Furthermore, as another sample, a silver halide color photographic light-sensitive material was prepared by sequentially coating the following layers on a paper support laminated on both sides with polyethylene from the support side.

The silver halide emulsions used in each of the photosensitive emulsion layers 1.3 and 5 were prepared by the method described in Japanese Patent Publication No. 46-7772, and each was chemically amplified using sodium thiosulfate pentahydrate. and 4-hydroxy-6-methyl-1,3,3a as a stabilizer.

7-chitrazaindene was used, bis(vinylsulfonylmethyl)ether as a hardener and saponin as a coating aid.

The sample prepared by the above method is referred to as sample 11.

In order to investigate the photographic characteristics of these samples 01 to 11, the following experiment was conducted.

First, each sample was subjected to three-color separation gradation exposure for sensitometry using a photosensitive needle (FWH model manufactured by Fuji Photo Film Co., Ltd., color temperature of light source: 3200°K). The exposure at this time was 250 CMS with an exposure time of 0.1 seconds.
The exposure amount was set to .

After processing, the density of the obtained yellow color image was measured and its maximum density (Dmax) was obtained. The results are shown in Table 2.

Furthermore, the above-mentioned samples 01 to 11 were separately exposed to uniform gray light using the photosensitive needle described above, and subjected to the same treatment as the sensitometry described above to evaluate pressure-sensitizing muscles. The results are shown in Table 2. However, the evaluation criteria at this time were the following four stages.

The exposed sample was processed using an automatic processor using the following processing steps and processing solution composition. However, in the composition of the color developer, the halogen ion concentrations of chlorine and bromine are shown in Table 2.
The process was carried out with the changes shown in the figure below.

Processing is done with a color developer, but the maximum density becomes low for those with excellent pressure-sensitizing muscles, and both problems cannot be solved at the same time.Processing 8.9 uses halogen with a low silver chloride content. With silver oxide emulsions, the decrease in maximum density is significant. Processing 10 to 13. In Processing 16 to 25, a high silver chloride emulsion containing the coupler of the present invention was processed with various halogen ion concentrations, but it was processed with a color developer that fell within the halogen concentration range of the present invention. It can be seen that only those with 200% pressure-sensitizing muscles have no pressure-sensitizing muscles and have excellent maximum concentration. Processes 14 and 15 are silver halide emulsions with a low silver chloride content, and even though the halogen ion concentration in the color developer is within the range of the present invention, the maximum density is inferior.

Furthermore, when the halogen ion concentration of the present invention is used, the maximum concentration is improved, which can be said to be an unexpected effect.

After the above photosensitive material was exposed under the exposure conditions shown in Example 1, it was processed according to the processing steps of Example 1.

However, the processing solution composition of the color developer at this time was 5.5 g/l of sodium chloride/12 g/l of potassium bromide,
